I read that it is using hash in a different way. I think that it also has better evaluation than other free source code programs and of course history pruning gives it a significant advantage. I thought about joining a project of commenting fruit source code because there are a lot of files and I think that there are not enough comments to explain them see http://wbforum.volker-pittlik.name/viewtopic.php?t=3219&start=0 but after I saw that nobody except me is interested in it based on no positive response to my posts in the winboard forum I lost motivation to do it. Note that I looked in part of the code and I will be happy to help people with some comments but only if more people join this project. Without more people if I decide to comment fruit I am going to keep the knowledge only for myself. I think that good comments should translate the code to human language and they do not need to be inside the code. The model that I like to have is that for every cpp file there is going to be txt file that explain it for example fruit has square.cpp and square.h and people who want to read fruit may do better if they read first square_comments.txt before they look at the code.
